Thescale factor used to build a model of a car is1/20.The area of sheet metal used to cover the outside:361cm^?

a.If the length of the model car is 18.3 cm, what is the actual length of the car?


b.What is the actual area of the metal sheeting used to cover the car? Thescale factor used to build a model of a car is1/20.The area of sheet metal used to cover the outside:361cm^?
a)18.3*20=366cm


b) l*b=361cm^2 hence actual area = 20l*20b =400*l*b = 400*361


=144400cm^2
